TOPIC:

Hi all wih out a manual just wanting to know what and where it the triggering mechanism for the spark on a 1982 kz250. I have a cdi/ignition module and a coil and a voltage regulator, but where or what triggers the voltage for the coil to cause the spark. There must be some sort of sensor pick
and rotor. Don't know where this may be unless it's all electronic but still should have some sort of sensor triggerinig mechanisim. I have voltage at both sides of coil as well as red and yellow terminals of the ignition module but still no spark. I also have apparently a faulty soLenoid as I have to short it out across battery terminals to get it to crank but that's another problem, as he starter button doesn't crank the motor.
Suggestions would be of some help.
Thanks.☺☺

I know virtually nothing about KZ250's, but the points or ignition igniter, if electronic ignition, should be on the end of the camshaft behind the big round cover cover on the LHS of the bike at the top of the cylinder head. (left, as if you are sitting on the bike,)

Thanks redhawk, I thought that might be where it was too but apparently it's not. I removed hat cover and it's the access port for the camshaft sprocket only nothing more. So I'm still in the dark as to where it would be. There has to be something such as a sensor something to fire the ignition module to energize the coil etc, but I can't find any hung as yet. I know nothing about this little beastie either. I'm looking for a reasonably priced manual now also.

I'm certain the points were there on the older model, but it looks like the electronic ignition version picks up a signal down where the generator is mounted from looking at the parts diagrams, but there really is very little information about these bikes on the internet. I think it works, with a flywheel pick-up that sends a signal to an igniter unit, the, the igniter unit then uses the engine speed to calculate the timing and tells the coil to fire at the appropriate moment. If you look where the generator is, I think you should be able to see some sort of pickup. I think it's called a "pulsing coil" in the parts book and is part number 59026.

Thanks Redhawk forntne reply. Yes it seems there is very little online about this particluar model. I asked at local bike shop and was told to look for pickup at alternator coil side cover. Just have to determine why no spark whether pickup coil not sending signal, ignitier which was replaced with a supposed working one from used bike purchased online or something else. I have an issue wih starter sloenoid currently so have to bypass it to get starter motor to crank bjt I'll fix that once i know i have spark.

Thanks formthe info redhawk. i'll check iinto that as soon as the cold weather abates. I did obtain a manual online however it was for the older model with the stanadard ignition not my model with the electronic ignition, so isn't much good to me in that particular area. I still have to replace the starter solenoid, and get the horn button to work. I still also have to check why I don't have spark.

Search for some posts by MFolks. He has posted some useful electrical system diagnostics and general maintenance. They may even be in the file base.

Thanks Texas KZ, well found some problems but now created some new ones.
I replaced the suspected cdi module sith a supposed used working one, still no spark, checked pulser pickup coil in left side cover (found open circuit there so replaced that), still no spark, investigated wiring diagram for cdi connector found potential differences there still trying to decipher wiring pin out versus correct wires to conndct to proper pins on cdi.
Still puzzled ogher than either the ignition coil is no good and or usec cdi module no good either.?

Hi Redhawk4 well apparently the pickup or pulser coil on this particular model is sorta where you mentioned but not at the top of the cylinder head but in the left side cover itself mounted inside the cover. I replaced this with an aftermarket one from a local bike shop and found potentially the wired in the cdi plug connector reversed so swapped them around and still no spark

No eBay APP ID and/or Cert ID defined in Kunena configurationSimilar to the one in this link.

are you getting 12v to your cdi and coils?

Hi punisher11b, yes sort of I measured 11.78v on each side of coil and something like that at the CDI but need a wiring diagram to ensure which wires to test there. I seem to recall yellow w orange is one.
I first found that this bike wasn't getting the required 500 or so ohm reading from the pickup/pulser coil connections.
So I got an aftermarked replacement and installed it. Then from a diagram made relating to the pinout of the CDI I drew an existing wiring connection to illustrate color of wires in each place. Owner and mechanic of local bike shop seemed to think the pickup connections as well as the +ve and -ve connections of the coil were reversed. So I carefully removed the connections (saftey pin works well) and connected them loose out of the plastic connector to see if that made any difference. NADA??
I'm stumped. everything works on this bike so far except spark, horn and starter solenoid which I'm currently bypassing for now. I haven't actually had this bike running yet need spark first then I can add fuel later? Lol
